Axiom Swiftui Search Ref

A search implementation reference for SwiftUI's `.searchable` modifier and related patterns. It's one piece of the larger axiom-swiftui suite, which covers everything from view updates and navigation to layout and performance. The main skill file includes a routing table that points to search-ref.md for search implementation tasks, alongside 15 other specialized references. The anti-rationalization section notes that search has six specific gotchas worth knowing about, which matches the pattern of other domain-specific guides in the collection. If you're wiring up search in SwiftUI and want to avoid the common mistakes, this is the reference to pull.
